(129, 207, 8019)-Net in Base 4 — Upper bound on s

There is no (129, 207, 8020)-net in base 4, because

the generalized Rao bound for nets shows that 4^mÂ â‰¥ 42490 161023 551140 977893 224483 055436 909694 894773 316865 683523 788145 947929 211835 680164 161725 872747 753626 142455 174157 674052 541160 > 4²⁰⁷ [i]
